Matlab - My Basic Structure for Editing Videos

The Basic Strucutre i use to edit Videos. Video Editting and Video Analysis in matlab should be done the same way as Image Editting and Anlaysis however theres a slight difference when doing this in Videos;

The steps required for video editting:

1. Identify your input Video
2. Expound the video by assuming each frame is an Image
3. Perform some image editting or analysis
4. Paste all the processed Images in a single sequence
5. Create a new Video

The following is a structure ill use throughout, Notice the "Orange" Section that will change in each implementation.

fin = 'rawVideo.avi'; %input File name to be changed
fout = 'movie2.avi'; %output File name to be changed

%get the File info
fileinfo = aviinfo(fin);
%get the number of Frames
nframes = fileinfo.NumFrames;

aviobj =
avifile(fout, 'compression', 'none', 'fps',fileinfo.FramesPerSecond);

for i = 1:nframes %You may need to limit the nFrames, may result in a large file size
%Read frames
from input video
mov_in = aviread(fin,i);
im_in =
frame2im(mov_in);

%Do processing on each frame of the video

%TO DO.....


%Write frames to output video
frm =
im2frame(im_out);
aviobj = addframe(aviobj,frm);

i %Just to display frame number you can ommit
end;

%Don't forget to close output file
aviobj = close(aviobj);
return;
